I have released four new chatbots. My chatbots, called Betabots, use Xaiml instead of AIML. I was here on this site a few months back and I referred to my chatbot engine as ProgramPY-SH because it was a Unix-shell/Python3 hybrid. Well, I now call the engine Pysh (pronounced Pie-SH). It is entirely Python3. As for Xaiml v1.8b, it will no longer try to be backwards compatible with AIML. The Betabots are hosted on the following links.
